There are a lot of variables in this.
First, if on July 4, 2017, you were told that a year and a half from then that we'd be starting threads disappointed about him while he was averaging 21 points per game, and averaging more points per 36 minutes than anyone from this franchise since Karl Malone's '99-'00 year, then you'd probably be flabbergasted, even if he's only shooting 41%.
Second, he has absolutely struggled. He doesn't appear as "dominant" as he had been. I think there are a lot of explanations for that. He's scouted, and the end of last year we came together strong. Has anyone seen our offense? It's terrible. Who does the defense have to focus on? Do you let Donovan run into the lane, or do you collapse and roll the dice on a kick out to Rubio? Of course Rubio will be open. I think there's a huge mental component and he's forcing a number of issues and not able to relax. When he went to the line for the last time last night, he looked nervous. It's hyped that he's always talking to guys on how to improve. I think he needs to stop listening to people for a while as I think he's over thinking this. I also think he needs more time on the floor with Korver. I'm not sure what the actual numbers are, but he's spending a lot of time in that starting unit that has only Joe Ingles as a floor spacer. He needs more time with Korver and Crowder lineups.
Also, with a few exceptions, it seems a pretty significant amount of Australians here really seem to be peeved by Donovan. Yeah, he probably gets more slack than a lot of guys. Some of that is earned, though. But yes, he's not above reproach. But I feel some of these Aussies have a two-pronged disgust with Mitchell, with the first being that they view his relationship with Simmons as a zero-sum game, and automatically assume any success for Donovan is a slight to Simmons. In similar fashion, they feel the role Donovan assumed last year is what Exum should have gotten, and they feel Quin and Donovan have somehow robbed Exum -- and Australia? -- from what they feel is rightfully theirs. Look, none of us want to see Exum not succeed, but around here we are Jazz fans first. We don't GAF about what team USA does. We also don't GAF whether the guy helping us win games is a Utah native, an American, or even if he were Dutch -- hell, most of us here would even be happy and supportive if our very own dutch could come in and drop 20! The fact is, you guys coming here only for Exum haven't been here for the Corbin era. You're not familiar with CJ Miles, or Morris Almond, or DeShawn Stevenson, or Curtis Borchardt, or Raul Lopez, or the disappointment that was AK. Nor have you watched two opportunities at a title disappear. So, yeah, you're walking into a historical context where excuse us if we don't see Australian Saer Sene as the next Kobe. It's time to stop associating everything DM with Exum and Simmons.
